I don't currently feel up to taking progress pictures, but it's official: I have biceps! For the first time
ever, when I flex my arms, you can see differentiation between the muscle groups.
I pulled up a "before" picture I took at 145 lbs and my arms definitely look different now! Measurements on my arms are smaller than usual as well. I'm not at my goal weight quite yet and nowhere near my lowest weight ever, but I'm at the lowest body fat % I've ever reached and that really does make a big difference in clothing sizes and measurements.
